Police revealed Friday that the chemistry department detected the banned chemical weapon VX nerve agent on the eyes and face of Kim Jong Nam, who was poisoned Feb. 13 at the Kuala Lumpur airport. Police have said two women, currently in custody, coated their hands with the chemical and wiped Kim's face with it.

Subramaniam said Sunday the chemistry department's finding confirmed the hospital's autopsy result, which suggested a chemical agent caused "very serious paralysis" that led to death "in a very short period of time." He said the VX agent can lead to death very quickly in high doses.

Subramaniam says there have been no reports of anyone else being sickened by the toxin since the attack.
